◆In the mode of wireless lighting, the following items can be seton the remote flash.

●Communication Channels:You can select one from the 4 channels. Please remember toset the same channel numbersimultaneously for the instructor remote flash lamp.

●Group Name: It can be divided into three groups (A, B, C) at most.

●If another photographer using the same type wireless remote flash settings is coming closer to you, your remote flash may flash synchronously by accident due to the influence of the infrared signals sent out by that photographer’s instructor. To avoid this situation, please use a different channel number.

For more information about the remote flashsettings,please refer to your instructionmanual about the flash.

Restore to Factory DefaultSettings

Press the button of【SET】for 5s, then the instructor will be restored to factory default settings.
The flash groups A and B are TTLflash mode, exposure compensation value is 0, and the channel number is 1 for the factory default settings.

●About Standby: To save the battery power, the instructor will automatically turn off without operation for a certain time (If it’s connected to a compatible camera, the turning-off time will be decided by the standby time of the camera, if it’s not connected, the turning-off time is aroundfive minutes) and the LCD screen displays “STBY”.

Flashing Operation and Shooting Steps of theInstructor

◆As a variety of Nikon flashes are equipped with wireless flash function, hence you can use it like using normal TTL flashes to create a variety of lighting effects.

•Using the input settings of the instructor installed on the camera, the signals will also be transferred to the flashes controlled by the instructor. Therefore, you don’t have to operate the subordinateflashes during shooting.

• Flashes can be used as remote flashes: SB600, SB700, SB800, SB900, SB910, etc.

The following itemscan be set during the instructor operation:

•The flash mode of the subordinateflashes: TTL, AA, M- - - (flash canceled) and RPT (repeating) flash. Each group can be set respectively, except repeating flash;

• Group name (A, B, C);
•Flash outputcompensation (in the mode of TTL and AA);

• Manual flash output (M mode);

Precautions

•Support the subordinate flash by using the micro base (tripod socket is provided).

• Rotate the body of the subordinate flash using the reflection function to make its wireless sensor face toward the instructor launch window.

• The wireless signal may also be reflected by the walls indoors, so the position of the subordinate flash is unnecessary to be very precise.

•When the subordinate flash is placed, be sure to test the wireless operation before shooting.

• Do not place any obstacles between the subordinate flash and the instructor, because they may block the transmission of the wireless signals.

• The way of wireless control is the same even multiple remote flashes are used.

• If the remote flash turns off the power automatically, you can half press the shutter button to turn on the remote flash again.

●Available Flashes:

SB600, SB700, SB800, SB900, SB910

●Precautions for RPT Flash Operation:

• Be sure to use a new battery. Each time when the RPT flash is used, make sure the interval time is enough for the flash recycling.

• In addition, as the slow shutter speed is used, it is recommended to use a tripod to avoid the camera and flashshaking.

Items to be Set Flash Operation

●The following items can be set onSU800 for the RPT flash operation.

•Channel No. (1, 2, 3, 4);

•Group Name (A, B, C);
